egt probes

The dragster I have has an altronics "informer" in it . I am trying to find the compression fittings for the egt sensors. They have a 7/16-24 male thread above the compression ring and need to go to an 1/8 pipe thread weld in bung. Apparently the guy left the bottom part of the compression fitting in his headers, now they are gone. Anybody know where i can find these type of fittings?

Yes. Don't not make it anymore. Would have to special order and for the price they charged me for the compression fitting they use now (which is of the "$1.50 hardware store" variety::::"nut and ferrel") I do not want to special order...I was hoping it would be the version they used before. Don't get me wrong they have been very helpful with the outdated unit. Will look in MSC or McMaster Carr. thanks!!!!
